[0035] In order to facilitate understanding of the above technical solution of the present invention, the above technical solution of the present invention is described in detail below through specific operation modes and working principles.

[0036] In specific use, such as Figure 1-5 shown.

[0037] The water in the wastewater collection pool drilled by the coal mine drilling rig is transported to the inverted bucket-shaped area at the bottom of the shell 3 of the sedimentation separation component through the liquid inlet 4 and the liquid inlet main pipe 5. The high-concentration wastewater enters and exits the device through the liquid inlet 4 and is transported to the bottom of the device by the pipeline; the high-concentration wastewater is then dispersed to the inverted bucket-shaped area at the bottom of the shell 3 through multiple water diversion ports evenly arranged on the liquid inlet water diversion pipe 6; the high-concentration wastewater flows out from each water diversion port through the liquid inlet water diversion pipe 6; the flow rate of the high-concentration wastewater in the pipeline system of the liquid inlet main pipe 5 and the liquid inlet water diversion pipe 6 is greatly reduced. In the inverted bucket-shaped area at the bottom of the shell 3, the wastewater fluid achieves a relatively slow flow through the above-mentioned technical features. The flow rate of the wastewater fluid in this slow flow state is low, the flow is relatively stable, and it is not easy to have violent flow states such as turbulence, which helps to reduce the disturbance of suspended particles in the wastewater fluid, making them more susceptible to the influence of gravity and sinking; it plays a role in promoting the slow flow of the wastewater fluid.

[0038] As the amount of sewage in the shell 3 of the sedimentation separation component increases, the sewage quickly spreads upward and does not pass through the two-layer adsorption component composed of a number of grid plates 12. A portion of relatively large impurities are retained at the bottom of the sedimentation separation component. The cross-section of the grid plate 12 is in the shape of a staggered broken line wave trapezoid, and the cross-sectional shape is a sideways W-shape, so that the sewage fluid does not flow in a straight line in the area of ​​the two-layer adsorption component, but is guided by the specific shape of the grid plate 12 to spread upward along a curved or winding path. This special design increases the path length of the sewage fluid flow, thereby extending the sedimentation time of particles in the sewage fluid. At the same time, the meandering path also facilitates the interaction between suspended particles in the sewage fluid, increases their chances of collision and adhesion, and further enhances the sedimentation and adhesion effect of suspended particles in the sewage fluid.

[0039] When the particulate matter settles and accumulates to a certain amount, the auger 9 at the bottom starts to run driven by the mining pneumatic motor 10; the sludge settled at the bottom of the sedimentation separation component is squeezed out and discharged through the sludge discharge port 11; if the sludge impurity content is not high, the auger 9 does not need to participate in the work; when a certain amount of high-concentration sewage is excessive, it is discharged through the first sewage pipe 7 and the sewage outlet 8 at the bottom.

[0040] Part of the impurities that spread through the adsorption component are adsorbed on the grid plate 12; the sewage in the shell 3 of the sedimentation separation component continues to spread upward. An overflow pipe 13 is provided at the top of the sedimentation separation component; the floating oil in the sewage can be taken out at the same time of overflow; a liquid level meter 27 is provided on the top of the shell 3; when the water volume in the sedimentation separation component is insufficient; the system automatically starts the water replenishment device through the distribution box 26 and the intelligent control system to replenish water to the system. The water replenishment device includes: a water replenishment port 15, a water replenishment valve 16, a lower spray branch pipe 17 and an upper spray branch pipe 18, wherein the side walls of the lower spray branch pipe 17 and the upper spray branch pipe 18 are provided with a number of evenly distributed spray devices; the slow flow effect during the water replenishment process is continuously and effectively maintained.

[0041] In a slow meandering environment under the combined effect of the above-mentioned technical solutions, tiny particles suspended in the sewage fluid are more likely to collide due to their mutual proximity and slow relative motion. When the particles in these sewage fluids collide, they may adhere together due to surface forces (such as van der Waals forces). This process of particle collision and adhesion in the sewage fluid causes the particles to gradually aggregate to form larger particle clusters or flocs; as the particle clusters or flocs aggregate and grow, their density and weight also increase accordingly, making it easier for them to overcome the rising force of the sewage fluid and settle to the bottom area of ​​the shell 3. In this process, gravity plays a key role, prompting the particle clusters or flocs to sink in the vertical direction, thereby achieving separation from the sewage fluid, and then sedimentation occurs, and finally separated from the sewage fluid, settled in the inverted bucket-shaped area at the bottom of the shell 3 and discharged through the mud outlet 11 under the action of the auger 9.

[0042] The floating sewage liquid level of the sedimentation separation component is transported to the downstream filtering component through the connecting pipe 20 through the connecting branch pipe 31 and the water diversion port at the top of the grid plate 12.

[0043] The filter assembly is a backwash precision filter for mining, mainly including: a cylinder 21 and multiple filter elements 22 arranged in the cylinder 21. The precision backwash filter has multiple filter elements 22 built in; the filtering area of ​​filters of the same size is doubled; the filtering effect and the stability of the product are greatly improved; the filtered clean water is transported to the drilling water pipeline of the drilling rig through the liquid outlet 25 arranged on the side wall of the cylinder 21 to continue to be circulated by the drilling rig; so as to reduce the wear of the coal mine drilling rig and extend the service life of its spare parts; and reduce the occurrence of failure rate when the system is working.

[0044] When the equipment is shut down or under maintenance, the equipment has a built-in intelligent cleaning device to clean the system. The high-pressure nozzles at the bottom and top of the equipment begin to flush the grid plate 12 in the sedimentation separation component and the inverted bucket area at the bottom. After cleaning, the sewage is discharged through the first sewage pipe 7 and the sewage outlet 8. The equipment stops running or is in standby mode waiting to be started.

[0045] To sum up, with the help of the above-mentioned technical scheme of the utility model, through the technical optimization and improved design of the product of the utility model, the system has the advantages of high filtration accuracy, large processing capacity, high degree of automation, small system processing volume, etc., and the purified water is recycled to reduce the wear of the drilling rig and extend the service life of the drilling rig parts; thereby achieving the technical effect of reducing labor input, improving production efficiency, and reducing the failure rate of the drilling rig; in addition, it also effectively saves water resources and alleviates the problem of environmental pollution.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
